Most all the menu can be made gluten free (or already is). They have a variety of gluten free and gluten pastries in the window, and can substitute gf bagels for bagels and gf bread for croissants on the sandwiches. They are happy to change gloves and handle gluten and non separately, and bagged them all separately. We ate here three times while in Santa Cruz with 8 people (once with 12) and had most of the menu at some point, all delicious. Also excellent covid safety (no eating or ordering inside, masks required for restroom).
I do not know if they have separate toasters/grills but they do process gluten free items separately. No gf fryer because no fried food at all. Many vegan and vegetarian options but also actual bacon and such.
